Too much emphasis is placed on team comp in low elo
Like, just play your best champ for the role available. I've beaten Caits as Vayne, etc. Sure, counter picks are still a thing with equal skill, obviously. But, I'd rather have a champ that you are really good with instead of you playing Zed, which you have 0 games with, because "you went ap top and we can't have ap".
and
to deal with that situation.
